The international importance of invasive alien species (IAS) is highlighted by the Article 8h of Convention on Biological Diversity (CBD), 1992, which emphasizes on prevention of the introduction of species which threaten other species, habitats or ecosystems. A Global Invasive Species Programme (GISP) was launched to assemble and identify practices for the prevention and management of IAS. Among the various international instruments, CAB International plays a key role to provide technical support at international and national level in identification of new alien species, publication of distribution maps and databases. In India, invasive weeds infest extensive tracts of agricultural and forest land. Various aspects of control of alien weeds and pests are being dealt with by a number of authorities. Recently, several initiatives have been taken at national level to identify specific actions to mitigate the threat of IAS. The present study highlights the national and global status, regulatory mechanisms and management options of invasive aliens. A national strategy for their management in line with the IS Guiding Principles given by CoP 5 and 6 has been proposed with several steps involved in its mode of implementation. Legislative measures like the Destructive Insects and Pests Act (1914) have been reviewed and the Plant Quarantine Order (Regulation of Import into India) 2003 has been enforced from January 1, 2004 and Environment (Protection) Act (1986) has also been reviewed and amended periodically, but still there is a lack of cohesive policy and action plan to deal with IAS. An overview on the national system for management of IAS has been proposed involving all the stakeholders to deal with biological invasions in a step-wise manner and future line of action recommended.
